Ontheedge, I have a full factory nav system (with the 2006 gps map) for your GX if your interested. Leave your email and I will give you the details.
Excellent. Please email me at Jrassic@aol.com. Thanks.
Question:
I recently purchased a 03 GX470 without the nav system. I've looked at many aftermarket options and none look as professional as the factory installed ones. Does anyone know if there's a way to get the entire radio unit switched out for the Levinson system? How do you find the parts and who would install it?
